After a limited preview, OpenAI has launched the GPT-5.6 series and opened it to public use via ChatGPT, CODEX and API. Models Sol, Terra and Luna are priced per 1M tokens: Sol $5 input / $30 output; Terra $2.50 input / $15 output; Luna $1 input / $6 output.

OpenAI founder Altman said the company has made 'many adjustments' after communicating with government.

The State Council issued the 15th Five-Year Carbon Peak Action Plan, mandating energy-saving and carbon-reduction retrofits in traditional industries and targeting major energy-using equipment, installations and processes. Targets for the 15th Five-Year Plan period include: cut CO2 emissions per unit of value added at above-designated-size industrial firms by more than 17%; reduce energy consumption per unit of industrial value added by over 10%; and lower energy intensity per unit of GDP by about 10%. The plan calls for broad deployment of energy-saving and low‑carbon technologies and equipment, low‑carbon process innovation and digital transformation, stronger energy-conservation inspections and a sound energy-efficiency diagnostic mechanism for key sectors. Retrofits in key industries are expected to deliver at least 150 mln tonnes of standard-coal equivalent energy savings.
